Summary

Minilaparotomy technique (MLT) for aortic aneurysm repair significantly reduces intensive care unit (ICU) and hospital stays compared to standard transabdominal approaches. This minimally invasive method offers comparable safety without increased costs or need for advanced equipment.

Area of Science:

  • Vascular Surgery
  • Minimally Invasive Surgical Techniques
  • Abdominal Aortic Aneurysm Repair

Background:

  • Elective graft repair for infrarenal aortic aneurysm (AAA) and aortoiliac occlusive disease (AIOD) traditionally uses standard transabdominal (STA) approaches.
  • Minimally invasive techniques aim to reduce patient morbidity and hospital resource utilization.

Purpose of the Study:

  • To assess the clinical outcomes of a minilaparotomy technique (MLT) for elective infrarenal AAA and/or AIOD repair.
  • To compare MLT outcomes with those of the standard transabdominal (STA) approach.

Main Methods:

  • Prospective, nonrandomized study comparing MLT (n=23) with STA (n=21) for infrarenal AAA or aortofemoral bypass.
  • Exclusion of patients requiring concomitant major vascular revascularization.

  • Data collection included operative time, ICU stay, return to diet, and hospital length of stay.

    • Main Results:

    • No significant differences in age, operative time, or aneurysm size between MLT and STA groups.
    • MLT demonstrated significantly shorter ICU stay (1 vs. 1.8 days), earlier return to general diet (3 vs. 4.7 days), and reduced hospital length of stay (4.9 vs. 7.3 days).
    • Morbidity and mortality rates were comparable between the two groups.

    Conclusions:

    • Minilaparotomy technique for elective aortic aneurysm repair leads to reduced ICU and hospital stays and decreased postoperative ileus.
    • MLT is a cost-effective alternative, avoiding expensive equipment and extensive postoperative surveillance required for endovascular repairs.
